Auto Commissioning & Management System & Amount of Refrigerant Check Function
4) Cycle Status
Ŷ Things to Check: Cycle status of outdoor unit
Ŷ Error Code: None (showing "Check Required" on the result report)
Ŷ Determine the cycle status of each outdoor unit.
Ŷ When needing to check the cycle status of
outdoor unit, please check in the following order.
Is the discharge
temperature sensor of corresponding
outdoor unit normal?
While in the Auto
Commissioning & Management System
operation, the indoor unit has maintained
the THERMO ON state.
Is the system refrigerant level appropriate?
Check the valve/sensor
and compressor.
Check the discharge
temperature sensor and take action
(assembly status, connector,
resistance, etc.).
Ventilate the indoor air.
Adjust the refrigerant level
(add/remove).
Finish
Upon running the Auto
Commissioning & Management System,
are the values of valve/sensor and operational
current found to be normal?
* How to Measure Resistance
After separating the temperature sensor connector from PCB,
measure the resistance between two connector terminals.
